Why does the screen display less than 20 Amps while charging? Is it defective?
This is normal. The charger outputs max 20A only when the battery is low. As it fills, current automatically drops to prevent overheating. This smart protection extends battery life.
Charger won't detect the battery or start charging?
Your battery voltage might be too low to detect. Use Force Mode: Hold "MODE" for 6s (buzzer beeps), then hold "MODE" for 6s again. Charge for 5 mins to raise voltage, then replug power to resume normal charging.
